Vulnerability of Barley to African Pathotypes of Puccinia graminis f. sp. tritici and Sources of Resistance
The emergence of widely virulent pathotypes (e.g., TTKSK in the Ug99 race group) of the stem rust pathogen (Puccinia graminis f.sp. tritici) in Africa threatens wheat production on a global scale. Although intensive research ...
Crop evapotranspiration — a technique for calculation of its components by field measurements
A simple technique is described whereby standard field measurements of crop evapotranspiration (ET), evaporation from an uncropped soil (ES), green area index (G), the crop extinction coefficient (K) and above ground dry ...
Efficiency of alpha-lattice designs in international variety yield trials of barley and wheat
Use of an alpha-lattice design in 714 international yield trials of barley, durum wheat and bread wheat in 1990/91 to 1992/93 resulted in an average efficiency 18% higher than the randomized complete block design when ...
A comparative analysis of nonhost resistance across the two Triticeae crop species wheat and barley
Background: Nonhost resistance (NHR) protects plants against a vast number of non-adapted pathogens which implicates a potential exploitation as source for novel disease resistance strategies. Aiming at a fundamental ...
Hulless barley as a promising source to improve the nutritional quality of wheat products
In this study, efforts were made to utilize hulless barley (variety BHS352) to enhance the nutritive value of chapatti and biscuit made from wheat flour. Barley flour was added to wheat flour in different ratios (5 to 30%). ...
Intercropping wheat and barley with N-fixing legume species: a method for improving ground cover, N-use efficiency and productivity in low input systems
Two cereal cropping systems are described which, through the introduction of a leguminous intercrop, increased productivity, nitrogen output and ground cover of the systems in the absence of added nitrogen fertilizer. ...
Salt Tolerance in the Triticeae: K/Na Discrimination in Barley
Concentrations of ions were measured in the youngest fully-expanded leaves of Triticum aestivum, T. durum, Hordeum vulgare, H. spontaneum, Secale cereale, and Aegilops squarrosa accessions grown in hydroponic culture in ...
Wheat and barley seed system in Syria: How diverse are wheat and barley varieties and landraces from farmer’s fields?
The present study described the diversity of wheat and barley varieties and
landraces available in farmer’s fields in Syria using different indicators. Analysis
of spatial and temporal diversity and coefficient of parentage ...
Farmer'S Seed Sources And Seed Quality: 2. Seed Health
The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were ...
First Report Of Wheat Dwarf Virus And Its Vector (Psammotettix Provincialis) Affecting Wheat And Barley Crops In Syria
A field survey covering the major cereal-production areas of Syria was conducted during May 2009. A total of 938 wheat and 971 barley samples with typical symptoms of viral infection were collected from 45 wheat and 58 ...
